Abstract This work considers the cooperative trajectory-planning problem along a double lane change scenario for autonomous driving. In this paper, we develop two frameworks to solve based on distributed model predictive control (MPC). The first approach solves single nonlinear MPC problem. general idea is introduce collision cost function in optimization at planning task achieve smooth and bou...

in order to determine the effect of valsalva maneuver and head rotation on the internal jugular vein (ijv) diameter and cross-sectional area and overlap with the carotid artery (ca) and find the best technique for safe cannulation of the ijv and decrease the risk of ca puncture, the diameter of both the ijv and the ca and percentage of overlap between the two vessels and cross-sectional area of...

The behaviors of heavy vehicles drivers in mandatory and discretionary lane changes are analyzed in this paper. 640 mandatory and 2,035 discretionary lane change events were extracted from a naturalistic driving database. Variations in gap acceptance and lane change duration were investigated. Statistical analysis showed that mandatory lane changes are more aggressive in gap acceptance and lane...

Automakers are trying to make vehicles more intelligent and safe by embedding processors which can be used to implement “by-wire” applications for taking smart decisions on the road or assisting the driver in doing the same. Given this proliferation, there is a need to minimize the computational capacity required without affecting the performance and safety of the applications. The latter is es...

Traffic scene understanding is an important part of future advanced driver assistance system (ADAS). In this paper we present a probabilistic approach for this problem. We use Hidden Markov Models (HMMs) for modeling the spatiotemporal dependencies of traffic situations. The parameters of the individual models are learned from a data base, generated by a professional driving simulation software...

In this study, stability control of a three-wheeled vehicle with two wheels on the front axle, a three-wheeled vehicle with two wheels on the rear axle, and a standard four-wheeled vehicle are compared. For vehicle dynamics control systems, the direct yaw moment control is considered as a suitable way of controlling the lateral motion of a vehicle during a severe driving maneuver. In accorda...

Abstract The cooperation between an autonomous vehicle and a nearby is critical to ensure driving safety in the lane-exchanging scenario. trajectory needs be predicted, from which controlled prevent possible collisions. This paper proposes strategy for cooperate with by integrating prediction motion control. A method developed anticipate trajectory. Gaussian mixture model (GMM), together kinema...

The main object was to perform simulations using a realistic model of a truck and trailer passing over a flexible bridge structure. The bridge structure was simplified to a flat surface modeled using shell finite elements. Tire normal, lateral and longitudinal forces were applied to the bridge. Three driving cases were considered: straight forward driving with and without braking and a lane cha...

In this paper an active brake control to decrease the rollover risk of heavy vehicles is proposed. The brake system is activated when the vehicle comes close to rolling over. To enhance the performance of the active brake, this mechanism is extended with a prediction procedure, in which the critical values are predicted in advance using a short time interval. In order to predict an imminent rol...
